Background Information
LBP (lipopolysaccharide-binding protein) is a serum glycoprotein belonging to the BPI/LBP/Plunc superfamily and BPI/LBP family. It is an acute-phase protein, predominantly synthesized by hepatocytes. LBP is present in normal serum at concentrations of 5 to 10 μg/ml, rising up to 200 μg/ml 24 h after induction of an acute-phase response. LBP binds to the lipid A moiety of bacterial lipopolysaccharides (LPS) which is a glycolipid present in the outer membrane of all Gram-negative bacteria, and acts as an affinity enhancer for CD14, facilitating its association with LPS.
Properties
| Storage Instructions | All the reagents are stored at 2-8℃ for 6 months or -20℃ for 12 months. Refer to the protocol for further storage instructions. |
| Synonyms | Lipopolysaccharide-binding protein |
FAQ
1、我的样本稀释液有限，如何处理稀释倍数较大的样本？
我们建议您对样本进行梯度稀释。例如，人血清样本需要1000000倍稀释时，您可以分3个梯度，每个梯度100倍，进行稀释：
第一步：取2 uL人血清样本，加入198 uL样本稀释液，混匀得到100倍稀释的人血清样本
第二步：取2uL 100倍稀释的人血清样本+ 198 uL样本稀释液进行稀释，混匀得到10000倍稀释的人血清样本
第三步：取2uL 10000倍稀释的人血清样本+ 198 uL样本稀释液进行稀释，混匀得到1000000倍稀释的人血清样本。
如果样本需要进一步稀释，您可以使用更多梯度。除了我们推荐的样本稀释液，不建议您使用其他溶液或者水稀释。如果您的样本稀释液仍然不足，请联系我们的客服为您提供更多样本稀释液。
2、我没有恒温振荡器，这会对实验时间和结果产生影响吗？
如果您没有恒温振荡器，完成这个实验大约需要 2.5 小时。在加入抗体混合物后，我们建议您将板条37℃下静置孵育2小时。在加入 TMB 后，您只需让板条37℃下静置孵育15分钟即可。我们的研发人员通过对比实验已经证明，尽管信号会略有降低，但您仍然可以获得有效的实验数据。
